[Plugin: Promotion Slider] Pulling all posts

I really like how this slider works and have implemented it on my page. However, when I go to my archives page, it pulls every post (not in the promotions category even) and won’t show an image. It works on author archive page, custom post template archive page, and my homepage, but it won’t work on just a standard category page. Any suggestions?
